Scientists stillaremysteries of the history, whichcan not give alogical explanation.

The first stone calendar

In the Sahara Desert in Egypt are the oldest known astronomically aligned, the stones in the world: Nabta (Nabta). For a thousand years before Stonehenge, people built a stone circle and other facilities on the lake, which has long dried up. More than 6,000 years ago, the stone slabs three meters high was dragged more than a kilometer to build this place. Pictured rocks - only part of the complex, which has been preserved. Although at present the Egyptian Western Desert completely dry, it was not so in the past.

There is good evidence that in the past there were a few wet cycles (when up to 500 mm of rain falls in a year.) Refers to the last interglacial period and the beginning of the last glaciation, it was about 130,000 to 70,000 years ago. During
this period, the area was a savanna and support the lives of many
animals such as extinct buffalo and large giraffes, antelopes and
gazelles different species. Starting around the 10th century BC, this area of ​​the Nubian Desert began to receive more rain, filling the lake. Early humans may region attracted sources of drinking water. Archaeological
findings may indicate that human activity in the area is known, at
least somewhere in the 10 th and the 8 th millennium BC.

The highest technology of stone

The
second group of findings that put the puzzle to scientists, are
artifacts created after the today's time of the appearance of man on
earth. But the technologies that were used in their creation, we have become known recently or are unknown so far. The most famous find of this group are crystal skull found in 1927 during excavations in Belize City Maya Lubaantuma. Skull carved from a piece of pure quartz and measures 12h18h12 centimeters. In 1970, the skull was analyzed in the laboratory by "Hewlett-Packard". The results were stunning. The skull was created without following the natural axis of the crystal, which is impossible in modern crystallography. When working on the skull does not use metal tools. According
to the restorers, first quartz Hacked diamond chisel, and then for a
more thorough treatment of the crystalline silicon used sand. To
work on the skull spent about three hundred years, which may be
perceived as an incredible example of patience and recognize the use of
unknown high technology. One
of the experts, "Hewlett-Packard" said the establishment of the Crystal
Skull is not a question of skill, patience and time, but it's just not
possible.

Hammerof the purestiron alloy

Puzzling enigma to science is ... ordinary-looking hammer. The metal part of the hammer has a length of 15 cm and a diameter of about 3 inches. He literally sinking into the limestone age of 140 million years, and is stored together with a piece of rock. This miracle caught the eye of Mrs. Emma Hahn in June 1934 in the rocks near the American town London, in the state of Texas. Experts who examined the find, rendered a unanimous conclusion: hoax. However,
further studies with a variety of academic institutions, including the
famous Battelevskoy Laboratory (USA), have shown that things are much
more complicated. First, the wooden handle, which planted the hammer outside already petrified, and inside and does become coal. So, too, her age millions of years. Second,
experts Metallurgical Institute in Columbus (Ohio) astonished the
chemical composition of the ground: 96.6% iron, 2.6% chlorine and 0.74%
sulfur. No other impurities could not be detected. So pure iron did not get in the history of the earth metals. In
the metal found no bubble quality iron, even by modern standards,
extremely high and causes a lot of questions, as the content is not
found metals used in the steel industry in the production of different
grades of steel (such as manganese, cobalt, nickel, tungsten, vanadium or molybdenum). Also there are no impurities, and the percentage of chlorine unusually large. Astonishing
that the iron found no traces of carbon, while the iron ore from the
Earth's field always contains carbon and other impurities. Generally speaking, from the modern point of view, it is not of high quality. But here's what detail: iron "Texas Hammer" does not rust! When in 1934 a piece of rock chipped rocks with ingrown tool, metal in one place is very scratched. And over the past six-plus years on the scratch does not appear any signs of corrosion ... Estimated
Dr. K.E.Bafa, director of the Museum of Antiquities minerals, which
holds this hammer, the find is from the early Cretaceous period - from
140 to 65 million years ago. On the current state of scientific knowledge, mankind learned to make such tools only 10,000 years ago. Dr.
Hans-Joachim Tsilmer from Germany, for the mysterious discovery in
detail, concludes: "This hammer is made by an unknown technology."

Fossil nail

However, most often in the rock are objects, their appearance similar to nails and screws. In
the XVI century, the viceroy of Peru kept in his office a piece of
rock, which was strong in 18-inch steel nail found in the local mines. In 1869, in Nevada, in a piece of feldspar raised from great depths, found metal screw length of 5 centimeters. Skeptics
believe that the emergence of these and many other items can be
explained by natural causes: a special kind of crystallization of
mineral solutions and melts, pyrite formation of rods in the voids
between crystals. But
pyrite - is iron sulfide, and at the turn yellow it (so it is often
confused with the gold), and has a clear cubic structure. Eyewitnesses
findings clearly indicate iron nails, sometimes covered with rust, and
pyrite formation rather be called gold, instead of iron. Also,
there is speculation that rodlike NIO - is fossilized skeletons
belemnite (invertebrate marine animals that lived at the same time of
the dinosaurs). But the remains of belemnites are found only in sedimentary rocks, and never in the root, such as feldspar. They also have a strong skeletal form, and confusing them with something else impossible. It
is sometimes argued that gvozdeobraznye NIO are the melt fragments of
meteorites or fulgurity (thunderbolts), obtained by a lightning strike
in the rocks. But finding a splinter or trail left millions of years ago, is extremely problematic. If the origin of gvozdeobraznyh NIO still possible to argue, that on some findings can only shrug.
